高血压、浮肿、蛋白尿是妊娠中毒症三大症状,现在仍未否定作为一个综合症的概念。但由于进行了细致监护、母体死亡显著减少,而使本症成为宫内胎儿发育障碍或胎儿窘迫的主要因素,因之高血压作为胎儿损害主要因素而被重视。现在有从肾素-血管紧张素-醛固酮系统(RAA),血液纤维凝固系统以及子宫内压和循环方面,进行病理生理的研究。欧美不但研究胎盘局部缺血,也从母体循环血液量或血管的感受性方面进行探索。一般传统的研究方向是母体内在环境和疾病所表现的特征。本病多发于初产妇,羊水过多症、多胎妊娠。本文就妊娠末期至临产时循环动态的变化,尤其是 Hypertension, edema and proteinuria are the three major symptoms of gestosis, and the concept of syndrome as a syndrome has not been denied so far. However, due to meticulous care, maternal death decreased significantly, leaving the disease as intrauterine fetal developmental disorder or fetal distress of the main factors, as a major factor of fetal damage as a result of hypertension has been valued. There are now pathophysiological studies from the renin-angiotensin-aldosterone system (RAA), hemagglutination system, and intrauterine pressure and circulation. Europe and the United States not only the study of placental ischemia, but also from the maternal circulation of blood volume or vascular susceptibility to explore. The general traditional research direction is characterized by the internal environment and disease in the mother. The disease occurs in early maternal, polyhydramnios, multiple pregnancy. This article is about the dynamic changes of circulation during late pregnancy to labor, especially
